Fuse ESB - Developing Applications Using JAX-WS [DRAFT]

Generating WSDL

Using the command line tool

Once your code is annotated, you can generate a WSDL contract for your service using the java2ws command's -wsdl flag. For a detailed listing of options for the java2ws command see java2ws in Web Service Tool Reference.

Using Ant

To call the WSDL generator from Ant use the java task to execute the org.apache.cxf.tools.java2ws.JavaToWS class and pass -wsdl as one of its arguments. Example 1.18 shows a sample Ant target that calls the WSDL generator.

Example 1.18. Calling the WSDL Generator from Ant

<project name="java2ws" basedir=".">   
   <property name="fsf.home" location ="/usr/myapps/fsf-trunk"/>
   <property name="build.classes.dir" location ="${basedir}/build/classes"/>

   <path id="fsf.classpath">
      <pathelement location="${build.classes.dir}"/>
      <fileset dir="${fsf.home}/lib">
         <include name="*.jar"/>
      </fileset>
   </path>
      
   <target name="WSDLGen">
      <java classname="org.apache.cxf.tools.java2ws.JavaToWS" fork="true">
         <arg value="-wsdl"/>
         <arg value="service.Greeter"/>
         <classpath>
            <path refid="fsf.classpath"/>
         </classpath>
      </java>
   </target>
</project>

	Important
	You must set the Java task's fork to true.

Example

Example 1.19 shows the WSDL contract that is generated for the SEI shown in Example 1.7.
